This is a real thing. When I was benchmarking recruiting processes for a client, I was acting as a candidate for another company. I spent a minute and a half with who I thought was a human recruiter, which later on I found out was a bot.
Growing numbers of job applicants are no longer facing a human person in their first interview. Instead, candidates are confronted with AI chatbots designed to screen applications and assess answers before involving a human recruiter.
